Focus On Leveling
Early on you're going to feel weak, because you don't have strong equipment. It isn't until level 10 that you can make your first set, so prioritize that.

Gather Early and Often
You will need a lot of materials to build what you need to survive. So, getting buy with gathering resources after making a Hatchet and Pickaxe is well worth your time.

Keep an Eye Out
You will occasionally see a Point of Interest pop up on the world map. These are temporary, and have great rewards. You will want to finish them quickly if you want to get ahead.

Get a Backpack
Inventory is limited, but the Basic Backpack will increase your space by eight. Make sure to find the blueprint and then build a backpack early.

Build a Home Early
It is recommended that you build a 3 x 3 home to start. Then, furnish your home with the basics, including a Small Box for storage, a Garden Bed for food supply, and a Campfire to improve the value of your food.
